To all whom it may concern:

Be it known that I, citizen of the Swiss Republic, residing at New York,in the county of New York and State of New York, have invented new anduseful Improvements inFlyin -Machines,of which the following is a spec'cation.

My invention consists of a new and improved flying machine.l

The' invention relates to that type of airship or flying machine whichisheavier than air. f

My device is constructed by having a number of revolving frames with aseries of revolving planes or blades pivotally connected thereto.

The machine has a driving shaft adapted to be rotated by a suitablemotor or any other desirable motive power. This driving shaft isconnected by means of gears to a transmission shaft which revolves anumber of frames or arms having a series of planes or blades. Thetransmission shaft by a system of gears f differentratios rotates theplanes on slower speed than the frames or arms. Each of the revolvingframes or arms with its planes can be tilted and set to any angle bymeans of a handwheel with a worm and gear connection. The frames or arms-with their, planes can thus be adjustedand set independently of eachother to any required position, either for thepurpose of raising themachine, or one of the planes may be tilted as a rudder when steering,or they can be set on a proper angle to balance the machine, or theblades can be reversed to stop the machine and used as a brake'.-` y

In the accompanying drawings Figure 1 is a rear View of my machine. Fig.2 is a top or plan view. Fig. 3 isa horizontal sectional view taken onthe line w a: Fig. 1. The device consists of 'a platform which maybe ofany desired construction, either a flooring or a basket vor a frame likebody constructed of tubing, etc. In the construction shown I haveindicated at a a platform or flooring.

The driving s aft is designated at c and may be connected to a motor atd. Any suitable motive power may be used. vThe motor is notv shown. Inthe construction shown there are four uprights or standards b. At the'top of the is a beveled gear e meshing driving shaft c gear f on atransmis'- with a corresponding ARMIN HELrEn, a n

sion shaft g. The transmission shaft g has sleeves h surrounding it, andthese sleeves h' pass through and rest in bearings 4. The bea-rings 4form a part of the uprights b shown in Fig. 1. These sleeves h have ateach end a bifurcated frame z'. These bifurcated frames i have openings5 and through m these openings 5 passes a shaft m carrying frames orarms 'n and to whichvare pivotally fastened the planes or `Vblades 0.These metal frame, rectangular in shape and covered with canvas orsuitable material, orthe planes or blades may be made entirely of metalif desired with the pivots attached directly to the blades.

Motion is transmitted to the frames or arms carrying the planes orblades and also to the planes or blades themselves in the followingmanner, viz z-The bifurcated arms i of the sleeve z. have exteriorlyformed hubs 7 rigidly secured thereto and to each hub 7 is rlgidlysecured a gear 6. Through the hubs 7 and openings 5 therein extends theshaft m carrying the arms or fra-mes n which in turn carry the .planesor blades 0. On this shaft m is secured a gear Z meshing with the gearla which gearI lc is rigidly se cured on the transmission shaft g. Itwill thus be seen that motion of the transmission shaft g is by means ofthe gears lc and transmitted to the shafts fm. on which the frames hangvand the frames are thus rou fated.

I will now describe the rotation of the planes or blades themselves.This latter result is attained by the arm of the frame n which isnearest to the-transmission shaft g, having a series of bearings 8thereon. Revolving in these bearings 8 are shafts s, there being onevshaft for each blade or plane o as shown in Fig. 2. Each of these shaftss' has a gear 10 rigidly secured thereto which gears 10 co-act with thesteady or rigid gear 6 on the hub 7 and the bifurcated frame i of thesleeve 71.. On the farther end of each of the shafts s is al gear tmeshing with a larger gear w secured to the pivot of the plane or bladeo. This gear. u is larger than gear t, preferably twice the size, sothat the planes or blades revolve'more slowly than the arms or frames n.

The planes or blades are the frame or arms carrying so arranged in themthat they heel u and this gear u 1s rigidly 4planes or blades may beconstructed of a are always at right angles to each other, as

`the blades when in advance of the other blade of the pair.

The top of the driving shaft c has a frame like housing 7 shown in Fig.l in which are mounted steering wheels p having a worm'g as shown inFigs. 2 and 3, meshing with a worm wheel 'w on the sleeve h. Byturningthese steering wheels p the sleeve /L is turned on the shaft gand the revolving frames n with planes or bladesv o are correspondinglytilted to vany desired angle to obtain theforward motion of the machine,and by means of these wheels p the action of the machine may beyreversed and the planes or blades used to give the machine a backwardmotion or`to act as a brake, and the machine may also be steered, bychanging the position orthe operation of'one of the steerlng wheels towork in one direction and the, other steering wheel to work in theopposite direction or toremain stationary.

lIn the accompanying illustrations I have only shown one driving vshaftwith one transmission shaft carrying two frames or arms on each end andeach frame and arm has two planes or blades making four planes or bladesin all. Of course, if necessary or desirable, I inay have more than oneseries of driving shafts and transmission shafts so that .the machinemay carry as many planes or blades as desired.

'I do not wish to be confined to the construction of the gears which Ihave shown. Instead of the'beveled gears shown on the arms or frame, Imay use `if desired, in lieu thereof, a series of chains and sprockets.
